摘  要:目的探讨河南汉族人群基质金属蛋白酶(MMP-9)基因内含子上-1562C/T多态性与缺血性脑卒中出血转化的关系。方法应用聚合酶链反应一限制性片段长度多态性(PCR—RFLP)技术,检测84例缺血性脑卒中出血转化患者和138例年龄与性别均匹配的单纯缺血性脑卒中患者的基因型,比较MMP-9基因-1562C/T多态性各基因型及等位基因分布频率。结果缺血性脑卒中出血转化组MMP-9基因-1562C/T多态CT+TT基因型的频率17.86%(15例)显著低于单纯缺血性脑卒中组30.43%(42例),T等位基因的频率8.93%(15个)也明显低于单纯缺血性脑卒中组15.94%(44个),差异均有统计学意义(χ2=4.326、4.458,P=0.037、0.035)。MMP-9不同基因型与等位基因在出血转化中的相对危险度结果显示,CT+TT基因型的0R值为0.497(95%CI:0.255~0.967),T等位基因的0R值为0.517(95%CI:0.278~0.961),携带T等位基因的患者缺血性脑卒中后出血转化的危险性显著降低。结论MMP-9基因-1562C/T多态性可能与河南汉族人群缺血性脑卒中出血转化相关,T等位基因可能是该人群缺血性卒中出血转化的保护因子。Objective To investigate the relationship between matrix metalloproteinase-9 (MMP-9) gene -1562 C/T polymorphism and hemorrhagic transformation (HT) from (IS) in Chinese Han population in Henan province. Methods The promoter -1562 C/T gene polymorphism in 84 IS patients with HT and 138 age- and sex-matched IS patients without HT were tested by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The genotypes and alleles frequencies of -1562 C/T polymorphism were analyzed. Results The frequency of CT and TT genotype and T allele was lower in IS patients with HT than in IS patients without HT (17.86% (15 cases) w 30.43% (42 cases), 8.93% (15 cases) w 15.94% (44 cases),χ2=4.326 and 4.458, P=0. 037 and 0. 035). The relative risk for HT from IS was decreased in patients with T allele than those withCTandTTgenotype [0.517 (95%CI: 0.278-0.961) w 0.497 (95%CI: 0.255-0.967)]. Conclusions The MMP-9 gene-1562C/T polymorphism may be related to hemorrhagic transformation of in Chinese Han population in Henan province. The T allele is a protective factor for hemorrhagic transformation of in the population.
